Golang，类型为字符串的变量 [英] Golang, variable with type from string

问题描述

是否可以从字符串类型创建变量?

Is it possible to create variable with type from string?

示例:
我有两种类型:

Example:
 I have two types:

type FirstType struct {
    ...
}

type SecondType struct {
    ...
}

// also I have a string variable
var1 := "Second"

我想创建类型为-String value + "Type"的变量:

I want to create variable with type - String value + "Type":

var variable = []var1+"Type" // slice of "SecondType"

这种情况下的预期结果是

Expected result is like in this case:

var variable = []SecondType

谢谢！

推荐答案

这是不可能的. Go不提供创建静态未知类型变量的功能.变量的类型始终是静态已知的.考虑改用接口.

This is not possible. Go does not provide functionality to create variables of types that are not known statically. The type of a variable is always known statically. Consider using interfaces instead.
